'Thisi's a division of my pending application for patent on a Labeling machine filed August 11, 1936; Serial No. 95,371;

The principal objects of this invention are to 5 provide'simple'and practicable meansfor pressure application withoutany motion of the wipers along the surfaces of the bottles while they are beingwiped and toprovide a straight line, re-

ciprocable pressure wiper.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. lis a plan of a preferred embodiment of this invention Fig. 2 is a front View thereof looking in the direction of the arrow 2 in Fig. 1, and

Fig. 3 is an end view of a feature thereof, looking in the direction of the arrow 3 in Fig. 2.

The machine is provided with the usual features. The rotary bottle carrier l3 and the bottle supports l9 and 19 operate to rotate the bottles intermittently.

The power for this part of the machine is delivered through a driven shaft 30 on which is a cam 32. The cam 32 reciprocates two pressure wipers 4| and 42, one for the body label and another for the neck label.

On a rod 14 is a head 94 which is provided with spokes carrying caps 95 one for each bottle on the bottle support l3. Each is held down by a spring 96 and guided by a short rod 91. Therefore, the moving downwardly of the rod '14 will move down these caps on the bottles and force the bottles down firmly on the carrier I3 under spring pressure. This is done by any suitable means properly timed. On the other hand, when the rod 14 is raised, the carrier I3 and head 94 will be raised to lift the bottles. The bottles are then carried by the carrier I3. There are two discs 99 which engage the bottles and help hold them in position while under the pressure of the wiping operation.

The cam 32 operates through a roller on a lever 36 to reciprocate a rod 31 and through a lever 38, reciprocates a pressure wiper frame 39, sliding on a rod 40. To keep the frame 39 from swinging, it is provided with a downward projection H which has a member III spaced at the center from the projection III] to receive a stationary guide H2. This is located below the frame 39. This frame also carries an upwardly extending arm H3 which also carries a plate H4 on the back to provide a space for receiving a support and guide H for the pressure wiper 4|.

this application April 8,

This support is provided with a spring H5 held by a projection H6, rod Ill and nut ll8to apply a little pressure back of this wiper. The neck wiper 42 is carried by an arm H8 adjustably connected with the plate H3 by a pin H9 and slot. The neck wiper is normally held back from the bottle neck, as shown, so as not to engage the neck before the bottle is clamped between the wiper 4| and discs 99. As the slide 39 moves forward the spring 5 yields and the neck wiper 42 engages the neck after the bottle is held in stationary position. On the reverse motion the neck wiper leaves the bottle neck before the body wiper 4| leaves the bottle.

The clamping down of the bottles by caps and the raising of the rotary bottle carrier so that the bottles will come to the right place for labeling and be held firmly in position has been described.

The pressure wiping is an important feature because it permits of the application of the labels to the bottle without any motion of the wiper along the surface of the labels. A bottle which has been operated upon by the pressure wiper is then moved forward by the rotation of its support. The labeling machine is provided with discs which engage the bottles to back them up while they are being labeled by the pressure method, thus avoiding considerable mechanism.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:

1. In a labeling machine, the combination of a vertical rod, caps carried by said rod for pressing down on the tops of articles to be labeled, a disc shaped body constituting a guide plate, an intermittently movable article carrier, and a pressure labeling device in a position to engage the label on an article to be labeled when it is held against said guide plate.

2. In a labeling machine, the combination of a vertical rod, caps carried by said rod for pressing down on the tops of articles to be labeled, two spaced discs for backing up the articles to be labeled, an article carrier, a pressure labeling device in a position to engage an article to be labeled when it is held against said discs, an operating shaft, a cam on the operating shaft, and means operated by said cam for moving the pressure labeling device under pressure up against the article to be labeled.

3. In a labeling device, the combination of a support for a bottle to be labeled, with a fixed guide rod, a slide on said rod, a lever, a cam for oscillating said lever, a rod pivotally connected with the lever to be operated thereby, a second leverconnected to be operated by the rod, means for connecting the second lever with the slide, an upwardly extending arm on the slide, a body label presser yieldingly carried by said arm, a neck label presser carried by said arm,'and=means for guiding the armeto move in arstraight line.

4. In a labeling device, the combination of a support for a bottle to be labeled, with a fixed guide rod, a slide on said rod, means for reciprocating said slide, an upwardly extending arm on the slide, a body label presser yieldingly carried by said arm, a neck label presser carried by said arm, and means for guiding the arm to move ina straight line.

5. In a labeling device, the combination of a support for a bottle to be labeled, with a fixed uide rod, a slide on said rod, a lever, a cam for oscillating said lever, a rod pivotallyconnected with the lever to be operated thereby, a second lever connected to-beoperated by the rod, means for connecting the second lever with the slide, an upwardly-extending arm on the slide, and a body label presser yieldingly carried by said arm.

6. Ina labeling device, the combination of a support for a bottle tobe labeled, with a fixed guide rod, a slide onsaid :rod, a lever, a cam for oscillating said lever, a rod pivotally connected with the lever to be operated thereby, a second lever connected to be operated by the rod, means for connecting the second lever with the slide, an

upwardly extending arm on the slide, a body label presser yieldingly carried by said arm, a neck label presser carried by said arm normally out of contact with the bottle neck, whereby it will engage said neck when the spring yields, and means for guiding the arm to move in a straight line.

'7. In a labeling device, the combination of a support for a. bottle to be labeled, with a fixed guide rod,.a slide on saidrro'dsmeansifor operating the :slide, "an upwardly extendmg arm on the slide, a body label presser yieldingly carried by rsaid arm, a neck label presser carried by said arm,

normally out of contact with the bottle neck, 'where'by i't will engage said neck when the spring yields, and means for guiding the arm to move in a-straight'line.

'8. Inalabelingmachine, the combination with a carrier -for advancing the articles to be labeled, means for moving the article support one step, means :for pressing labels on the article, rigid means for supporting the article at the back while the pressing means is operating, a neck label wiper, and meansiormoving the neck label wiper into-contact with the bottleneck after theJabel pressing means'has engaged the bottle and away from it before.

9. In a labeling machine, the combination of-a disc shaped body constituting a guide plate, an article carrier, .a pressure body labeling device in a ,position to engage the label on anarticle to be labeled when it is held againstisaidguide plate .to backit up, anecklabelpress'ing wiper and means for yieldingly pressing thenecklabel wiper against the neck of the article after the body labeling device has pressed the article against the 'disc shaped body.
